(Elsevier, 2023) Ede, Seren; Özbeyli, Dilek; Erdogn, Omer; Cevik, Ozge; Kanpalta, Fatma; Ercan, Feriha; Senerg, Goksel
Background and study aims: This study aimed to investigate the possible protective effects of parsley extract (Petroselinum Crispum; PC) against oxidative liver damage caused by bile obstruction in rats. Material and methods: Bile duct ligation (BDL) method was used to induce liver injury in rats. The rats were divided into the three groups each consisting of 8 rats; Sham-operated control (C), bile duct ligated + saline treated (BDL), and BDL + PC treated groups. PC extract was given at a dose of 2 g/kg orally for 28 days. Aspartate amino transferase (AST), alanin amino transferase (ALT), and bilirubin levels were analyzed in sera. In order to determine free radicals in liver injury, luminol and lucigenin chemiluminescence tests used. Oxidative stress was evaluated through superoxide dismutase, glutathione, malondialdehyde, Na+/K+-ATPase and 8-hydroxy guanosine levels. Furthermore, inflammation marker myeloperoxidase, apoptosis marker caspase-3, and fibrosis markers TGF- beta and hydoxyproline were investigated. The liver tissues were also examined for histological evaluations.Results: While PC treatment decreased AST and ALT levels which increased with BDL, oxidant damage parameters also decreased with this treatment. Conclusion: The present study, which is the first research for PC extract on cholestasis induced liver damage, demonstrated that PC extract could be a potential therapeutic agent against liver fibrosis and need further studies.

(International Society of Musculoskeletal and Neuronal Interactions, 2024) Reyhanıoglu, D.A.; Yıldırım, G.; Sengun, I.Ş.; Kara, B.
Objective:To evaluate the use of a computer-based biodex balance exercise system (BBS) on balance, neuropathic pain, clinical presentation and nerve function in patients with diabetic peripheral neuropathy (DPN). Methods: A total of 32 participants with DPN were randomly assigned in a 1:1 ratio to an intervention group (IG) or control group (CG). The IG performed exercises using the BBS twice weekly for 8 weeks, while CG were informed regarding diabetes self-management. At baseline and after study completion, participants underwent balance (postural stability and fall risk) and neuropathic pain assessment (DN4 questionnaire) and were screened using the Michigan Neuropathy Screening Instrument and nerve conduction test. Results: Among the baseline participants, 14 in the IG and 13 in the CG completed the study. Balance training improved postural stability (overall, p<0.001), fall risk (p<0.001), neuropathic pain (p=0.01) and symptoms (p<0.001), and clinical presentation (p=0.02), but not nerve function, within the IG. At follow-up, IG displayed significantly improved stability (p<0.001) and fall risk (p=0.02) and decreased neuropathic symptoms (p=0.01) compared to the CG. Conclusion: Computer-based balance exercises improve balance, pain, and clinical presentation of DPN, but not nerve function, in patients with DPN.

Prevalence of Obesity in Prepubertal and Pubertal With Turkish Population Type 1 Diabetes
(Springer Japan Kk, 2021) Ozkaya, Volkan; Eren, Erdal; Ozgen Ozkaya, Sebnem; Denkboy Ongen, Yasemin
To determine the prevalence of prepubertal and pubertal obesity in children and adolescents with type 1 Diabetes Mellitus (Type 1 DM). One hundred fifty children and adolescents aged 6-18 years with Type 1 DM who attended the Pediatric Endocrinology Polyclinic and were diagnosed with type 1 DM were included in the study. Tanner staging was used to estimate pubertal status. Age- and gender-specific body mass index (BMI) percentile between 85 and 95% was accepted as overweight and > 95% as obese. It was determined that the overweight prevalence rates in children and adolescents with type 1 DM were 13.3% and the obesity rate was 14.3%. It was found that while the overweight prevalence rates (14.1%) were higher in males, the obesity prevalence was higher in females (19.0%). The obesity prevalence rates at the prepubertal and pubertal stages were found to be 17.1% and 13.8%, respectively. The obesity prevalence at the pubertal stage was higher in girls (22.4%) than boys (3.9%) (p < 0.05). The rates both of overweight and obesity in boys decreased from prepubertal to pubertal periods, while those rates increased in girls. Our results indicated that the obesity prevalence in prepubertal and pubertal children and adolescents with type 1 DM was higher compared to healthy peers in the literature. The authors believe that the risk factors for obesity in this population should be determined and obesity-prevention programs for diabetes should be prepared.

Synthesis, Antimicrobial Evaluation, and Molecular Modeling Studies of New Thiosemicarbazide-Triazole Hybrid Derivatives of (s)-naproxen
(Wiley-v C H verlag Gmbh, 2022) Han, M. Ihsan; Ince, Ufuk; Gunduz, Miyase Gozde; Kucckguzel, S. Guniz
The discovery of new antimicrobial molecules is crucial for combating drug-resistant bacterial and fungal infections that pose a dangerous threat to human health. In the current research, we applied a molecular hybridization approach to synthesize original thiosemicarbazide-triazole derivatives starting from (S)-naproxen (7a-7k). After structural characterization using FT-IR, H-1-NMR, C-13-NMR, and HR-MS, the obtained compounds were screened for their antimicrobial activities against Staphylococcus aureus ATCC 29213, Escherichia coli ATCC 25922, Candida albicans ATCC 10231 and their isolates, as well. Although all compounds were found to be moderate antimicrobial agents, in general, their antibacterial activities were better than antifungal effects. Among the tested compounds, 7j carrying nitrophenyl group on the thiosemicarbazide functionality represented the best MIC value against S. aureus isolate. Finally, molecular docking studies were performed in the active pocket of S. aureus flavohemoglobin to rationalize the obtained biological data.
Ameliorative Effects of Myrtus Communis L. Extract Involving the Inhibition of Oxidative Stress on High Fat Diet-Induced Testis Damage in Rats
(Taylor & Francis Ltd, 2024) Coskunlu, Busra; Koroglu, M. Kutay; Hersek, Irem; Ertas, Busra; Sen, Ali; Sener, Goksel; Ercan, Feriha
The possible protective effects of Myrtus communis L. (MC) extract on a high fat diet (HFD)-induced testicular injury in a rat model were investigated using histological and biochemical methods. Wistar albino rats were divided into three groups: a standard diet control group; a HFD group; and an HFD+MC group. The HFD and HFD+MC groups were fed with a HFD for 16 weeks. MC extract (100 mg/kg) was given orally five days a week to the rats in the HFD+MC group during the last four weeks of the experiment. Leptin, triglyceride, high-density lipoproteins, cholesterol, estrogen, testosterone, LH and FSH were analyzed in blood serum. Sperm parameters were evaluated from the epididymis. Testicular morphology, proliferative, apoptotic and NADPH oxidase-2 (NOX2)-positive cells were evaluated histologically. Testicular oxidative stress parameters were analyzed biochemically. In the HFD group, lipid and hormone profiles were changed, abnormal spermatozoa, degenerated seminiferous tubules with apoptotic and NOX2-positive cells were increased in number, and sperm motility and germinal proliferative cells decreased compared to the control group. Moreover, testicular malondialdehyde, 8-hydroxy-2-deoxyguanosine and myeloperoxidase levels increased, whereas glutathione and superoxide dismutase levels decreased in the HFD group compared to the control group. All these histological and biochemical features were ameliorated by MC treatment of HFD-fed rats. In conclusion, HFD caused alterations in sperm parameters and testicular morphology by increasing oxidative damage and apoptosis. MC extract may have potential protective effects by inhibiting oxidative damage.

(Natl inst Public Health, 2022) Ozturk, Servet; Ozel, Ayse Serra; Ergen, Pinar; Senbayrak, Seniha; Agalar, Canan
Objectives: Human immunodeficiency virus (HIV) and hepatitis B virus (HBV) are the two leading viruses that cause the greatest number of virus-related morbidities in the world. HIV/HBV coinfection is correlated with high morbidity and mortality. For this particular reason hepatitis B vaccination is crucial for people living with HIV. Methods: Patients who are being followed-up for HIV/AIDS and who have received a hepatitis B vaccine in 4 HIV clinics over a 5-year time period have been studied. Our multi-centered, retrospective, cross-sectional and observational study investigates factors that affect hepatitis B vaccination immune response of individuals living with HIV. The patients have been studied for the parameters such as age, sex, CD4 count at the time of diagnosis or vaccination, HIV-RNA levels, comorbidities, vaccine dosage, success of immunization after vaccination, and the demographics of the patients who have and have not developed immunity. Results: Of 645 patients that are being followed-up in our clinics, 158 received hepatitis B vaccine; 39 of these 158 patients have been excluded from the study because they did not fulfil the inclusion criteria. Finally, 119 patients were evaluated in the study, 17 of the patients (14.3%) were females and 102 (85.7%) were males. The median age was 41.11 +/- 10.09 (min-max: 18-75). Twenty-three of the patients (19.3%) were at the stage of AIDS during diagnosis while 80.7% were at the stage of HIV infection. Ninety-one of the patients (76.5%) have been administered a single dose hepatitis B vaccine on the standard 0, 1st, 6th month vaccination schedule, whereas 23.5% were administered a double dose on the same vaccination schedule. When further evaluated to find whether the patient was able to develop sufficient immunity (anti-HBs >= 10), it was found that the immune response was statistically significantly higher in the patients whose CD4 count was greater than 200 at the time of the first diagnosis and vaccination (p = 0.05 and p = 0.001, respectively). The patients have also been evaluated according to the number of doses they received (1 vs. 2). The immune response of the patients who received two doses was statistically significantly higher (p = 0.041). Conclusion: We can conclude that in the patients with CD4 count less than 200 at the time of their diagnosis and vaccination a high dose recombinant hepatitis B vaccine should definitely be administered as the normal dose and higher dose have similar side effect profiles and the higher dose provides greater immunity.

(Elsevier Science inc, 2023) Anilir, Ender; Oral, Alihan; Atasoy, Alp; Civan, Hasret Ayyildiz; Topcu, Feyza Sonmez; Bayramoglu, Mert; Unal, Bulent
Background. Living donor liver transplantation (LDLT) has become an increasingly common surgical option because the number of cadaveric donors is insufficient to fulfill the organ needs of patients facing end-stage cirrhosis. Many centers are investigating different surgical techniques to achieve lower complication rates. We aimed to examine our complication rates in light of demographic data, graft data, and perioperative findings as a single-center experience. Methods. The study included one hundred and three patients who underwent LDLT for endvein, and bile anastomosis type rates; anhepatic phase; cold ischemia time; operation time; and blood product transfusion rates were analyzed. Biliary complications in patients with single or multiple biliary anastomoses, right or left liver transplants, and with or without hepatic artery thrombosis were analyzed statistically. Results. There was no significant difference in biliary complications between patients who underwent single or multiple bile anastomosis (P = .231) or patients receiving right lobe and left lobe transplants (P = .315). Although there was no statistically significant difference in the rate of portal vein thrombosis between the regular and reconstructed portal vein anastomosis groups (P = .693), the postoperative portal vein thrombosis rate was statistically higher in patients with left lobe transplants (P = .044). Conclusions. Vascular and biliary complication rates can be reduced with increasing experience.

Melatonin Improves Liver and Pancreatic Tissue Injuries in Diabetic Rats: Role on Antioxidant Enzymes
(Springer int Publ Ag, 2023) Ertik, Onur; Bayrak, Bertan Boran; Sener, Goksel; Yanardag, Refiye
PurposeMelatonin (Mel) is an indolamine mainly synthesized by the pineal gland and many other organs. It plays an important role in scavenging free radicals and stimulating antioxidant enzymes. The goal of this study was to investigate the effect of Mel and/or insulin treatment on oxidative liver and pancreas injuries in diabetic rats.MethodsMale Wistar albino rats were assigned into 5 groups. Group I: control animals. Group II: diabetes was induced via a single dose of STZ (60 mg/kg) administered intraperitoneally. Group III: diabetic rats treated with Mel (10 mg/kg/day). Group IV: diabetic rats given insulin (6U/kg) subcutaneously. Group V: diabetic rats that received insulin and Mel at the same dose and time. After 12 weeks of the experiment, the animals were decapitated, liver and pancreas tissues were collected.ResultsThe results indicated that reduced glutathione levels in liver and pancreatic tissue decreased, while protein carbonyl, advanced oxidized protein products and lipid peroxidation levels were elevated in diabetic group. Antioxidant enzyme activities decreased in liver tissues but increased in pancreatic tissues of the diabetic group. Administration of Mel, insulin or Mel + insulin reversed these biochemical changes in the diabetic animals.ConclusionThis work shows that in long-term oxidative stress conditions caused by STZ-induced diabetes, either Mel or Mel + insulin administration may improve the deteriorated oxidant/antioxidant system in both the liver and pancreas tissues. These results suggested that Mel alone or Mel + insulin treatments might have a significant role in protecting against liver and pancreatic damage in STZ diabetic rats via different antioxidant effects.
Unraveling the Persistent Renal Impact of Intrauterine Growth Restriction and Catch-Up Growth: Integrating Morphological Insights with Metabolomic Profiling
(Springer, 2025) Esrefoglu, Mukaddes; Koktasoglu, Fatmanur; Bayindir, Nihan; Cimen, Fatma Bedia Karakaya; Kirmizikan, Seda; Hekimoglu, Emine Rumeysa; Selek, Sahabettin
The study aimed to investigate the long-term effects of IUGR and consequent catch-up growth on metabolic health by using a comprehensive approach that included histopathological, immunohistochemical, biochemical, and metabolomics analyses. Sprague-Dawley pregnant rats either undergo bilateral uterine artery ligation or a sham surgery on the 19th day of gestation. The offspring reached catch-up growth, kidney samples were collected at postnatal weeks 2, 4, and 8 for analysis. IUGR rats exhibited a spectrum of changes including reduced glomeruli number, proliferating cell number, altered oxidative stress markers, various enzymes involved in Krebs cycle, mitochondrial dynamics, and energy metabolism. Examination of the 8-week-old cohort identified a broader spectrum of metabolic alterations, notably in the biosynthesis of phenylalanine, tyrosine, and tryptophan, phenylalanine, tyrosine, glyoxylate, dicarboxylate, pyruvate, alanine, aspartate, and glutamate metabolism, glycolysis/gluconeogenesis and citrate (TCA) cycle. Our metabolomics analysis provides insights into the potential disease susceptibility of individuals born with IUGR, including obesity, diabetes, hypertriglyceridemia, cardiovascular diseases, and mental retardation. These findings underscore the intricate interplay between intrauterine conditions and long-term metabolic health outcomes, highlighting the need for further investigation into preventive and therapeutic strategies to mitigate the risk of metabolic diseases in individuals with a history of IUGR.

Turkish Translation/Cultural Adaptation and Psychometric Analyses of the Affordances in the Home Environment for Motor Development-Infant Scale (ahemd-Is)
(Sage Publications inc, 2023) Apaydin, Umut; Eraslan, Rabia; Balikci, Aymen; Elbasan, Buelent
In this study we translated the Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) into Turkish, adapted the instrument culturally, examined its psychometric properties within a Turkish population, and identified its limitations. We administered the AHEMD-IS to families of 65 premature or full-term Turkish infants and repeated this testing for 17 families after one-two weeks to establish test-retest reliability. We calculated the Intraclass Correlation Coefficient (ICC) and Cronbach alpha coefficient to assess reliability, and we evaluated test validity using the Spearman's correlation coefficient and correlations with the Bayley-III motor development score. The Cronbach Alpha coefficient of the questionnaire was 0.846, and, for test-retest reliability, the ICC score was 0.830. The Turkish AHEMD-IS total score was moderately correlated with the Bayley-III fine motor development score (r = 0.469, p < 0.001), the Bayley-III gross motor development score (r = 0.533, p < 0.001), and the Bayley-III total motor development score (r = 0.526, p < 0.001). The Turkish version of the AHEMD-IS was found to be valid and reliable for children born prematurely or at full-term. The use of this questionnaire in Turkey will facilitate the creation of a home environment that will support motor development in children between 3-18 months of age.
The Effect of Simulation-Based Electroconvulsive Therapy Education on Perception and Knowledge of Nursing Students: a Semiexperimental Study
(Lippincott Williams and Wilkins, 2025) Dikeç, G.; Şan, E.Ö.
Objectives Despite the recognized benefits and safety of electroconvulsive therapy (ECT) for treating mental disorders, negative perceptions persist among both the public and mental health professionals. This stigma is often rooted in historical practices and media portrayals, despite modern advancements in the technique. This study aimed to assess the impact of simulation-based ECT education on nursing students' perceptions and knowledge regarding ECT before and after the procedure. Methods This study was planned to use a single-group pretest and posttest quasi-experimental design with a 3-month follow-up. Simulation-based ECT education involved 1 hour of theoretical instruction followed by hands-on learning using a high-fidelity mannequin. Final-year nursing students enrolled in a psychiatric and mental health nursing course were examined on their knowledge and perceptions of ECT before, immediately after, and 3 months following the intervention. Results Students reported statistically significant improvements in their perception and knowledge levels after participating in the simulation-based ECT education. The results were similar at the 3-month follow-up. Conclusions Simulation-based ECT education can be effectively integrated into both undergraduate and graduate nursing curricula to foster positive perceptions and enhance knowledge about ECT.

Investigating the Impact of Various Insole Applications on Balance and Postural Stability in the Elderly
(Elsevier, 2025) Ozturk, Basar; Ozdincler, Arzu Razak; Kocyigit, Ahmet; Kaya, Begum Kara; Kisa, Eylul Pinar
Objectives: Aging leads to physical and cognitive declines, notably affecting balance and motor skills, making falls a prevalent health concern among the elderly. Falls, a significant health issue among the elderly, often stem from these impairments. This study aims to investigate the impact of different insole materials, specifically cork and silicone, on balance and postural stability in the elderly. Methods: A randomized controlled trial was conducted at the Istanbul Barinyurt Elderly Care Center with 24 participants, divided into two groups to test cork and silicone insoles. Balance parameters, plantar pressure, the Timed Up and Go (TUG) test, and the Five Times Sit-to-Stand Test were used as measures. Data analysis was performed using the Mann-Whitney U and Wilcoxon tests. Results: Post-intervention, the cork insole group showed significant improvements in balance, maximum plantar pressure, and functional mobility tests compared to the silicone insole group. While both insoles enhanced certain balance parameters and walking performance, cork insoles proved more effective in key outcomes. Additionally, maximum plantar pressure for the cork insoles group decreased significantly, indicating better pressure distribution and potentially enhanced balance. Conclusion: Cork insoles are superior to silicone insoles in improving balance and postural stability among the elderly. This study supports using cork insoles as part of fall prevention strategies, emphasizing the importance of material properties in orthopedic insole design. Future research should explore long-term effects and integrate insoles with other postural stability methods for comprehensive elderly care.

Extracorporeal Shockwave Therapy Versus Graston Instrument-Assisted Soft-Tissue Mobilization in Chronic Plantar Heel Pain a Randomized Controlled Trial
(American Podiatric Medical Association, 2022) Pisirici, P.; Cil, E.T.; Coskunsu, D.K.; Saylı, U.; Subasi, F.
Background: Although there are studies showing that extracorporeal shockwave therapy (ESWT) and instrument-assisted soft-tissue mobilization methods are effective in chronic plantar heel pain (CPHP) treatment, there is a need for studies comparing these techniques. We compared the effectiveness of ESWT versus instrument-assisted soft-tissue mobilization using Graston Technique (GT) instruments in addition to stretching exercises (SEs) in CPHP. Methods: Sixty-nine patients were randomly assigned to three groups: ESWT+SEs (group 1), GT+SEs (group 2), and SEs only (control group) (ratio, 1:1:1). The SEs, twice daily for 8 weeks, were standard for all. Group 1 received low-intensity ESWT; in group 2, GT was the selected method. Visual analog scales (for initial step and activity pain), the Foot Function Index (FFI), the 12-item Short-Form Health Survey (SF-12), and the Tampa Scale for Kinesiophobia were used pretreatment, posttreatment, and at 8-week and 6-month follow-up. Results: Visual analog scale and FFI scores improved posttreatment and during follow-up in all groups (P < .001). Although effect sizes were greater in groups 1 and 2 than in the control group in initial step pain posttreatment and at 8-week follow-up, group 2 had the highest effect size at 6 months. Mean SF-12 scores in groups 1 and 2 improved on the post-treatment assessment. Furthermore, group 2 showed significant improvements in FFI scores compared with the other groups at 6-month follow-up (F = 6.33; P = .003). Conclusions: Although ESWT+SEs and GT+SEs seem to have similar effects on initial step pain posttreatment and at 8-week follow-up, GT+SEs was found most effective for improving functional status at 6 months in the management of CPHP. © 2022, American Podiatric Medical Association.

(Womens Health & Action Research Centre, 2024) Dulger, Ozlem; Dinmez, Sinem; Torun, Sebahat D.; Osmanoglu, Usame O.
This study aims to compare the sexual functions of couples undergoing assisted reproductive techniques (ART) with those conceiving spontaneously during pregnancy. A total of 102 couples participated in this cross-sectional study, with 68 couples in the spontaneous conception group and 34 couples in the ART group. Data collection was conducted face-to-face in the antenatal clinic using separate "Descriptive Information Form" for women and men, "Female Sexual Function Index (FSFI)" for women, and "Libido Scoring System (LSS)" for men. Descriptive statistical methods, Chi-square and Fisher exact tests, t-test, and Pearson correlation test were used for data analysis. It was observed that the mean FSFI total scores of women who conceived spontaneously and through ART during pregnancy were at a good level (>= 30), while the mean LSS scores of their partners were at a moderate level (5-7). No statistically significant distinction existed among the groups. Further research is advisable by adjusting the sample selection criteria, such as gravida, duration of ART treatment, and gestational age.

Synthesis and Evaluation of Novel Metacetamol Derivatives With Hydrazone Moiety as Anticancer and Antimicrobial Agents
(Wiley-v C H verlag Gmbh, 2023) Senkardes, Sevil; Atlihan, Irem; Cayir, Elif; Tiber, Pinar Mega; Orun, Oya; Nigiz, Seyma; Kucukguzel, S. Guniz
By exploiting the wide biological potential of the hydrazone scaffold, a series of hydrazone derivatives were synthesized, starting from N-(3-hydroxyphenyl)acetamide (metacetamol). The structures of the compounds were determined using IR, H-1 and C-13-NMR, and mass spectroscopic methods. The obtained molecules (3 a-j) were evaluated for their anticancer potential against MDA-MB-231 and MCF-7 breast cancer cell lines. According to the CCK-8 assay, all tested compounds showed moderate to potent anticancer activity. Among them, N-(3-(2-(2-(4-nitrobenzylidene)hydrazinyl)-2-oxoethoxy)phenyl)acetamide (3 e) was found to be the most effective derivative with an IC50 value of 9.89 & mu;M against MDA-MB-231 cell lines. This compound was further tested for its potential effects on the apoptotic pathway. Molecular docking studies was also carried out for 3 e in the colchicine binding pocket of tubulin. Additionally, compound 3 e also demonstrated effective antifungal activity, particularly against Candida krusei (MIC=8 & mu;g/ml), indicating that nitro group at the 4(th) position of the phenyl ring was the most preferable substituent for both cytotoxic and antimicrobial activity. Our preliminary findings suggest that compound 3 e could be exploited as a leading structure for further anticancer and antifungal drug development.
In Silico Evaluation of H1-Antihistamine as Potential Inhibitors of SARS-CoV RNA-Dependent RNA Polymerase: Repurposing Study of COVID-19 Therapy
(Turkish Pharmacists Association, 2024) Küçükgüzel, İlkay; Kulabaş, Necla; Hamdan, Mazın
Introduction: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), from the family Coronaviridae, is the seventh known coronavirus to infect humans and cause acute respiratory syndrome. Although vaccination efforts have been conducted against this virus, which emerged in Wuhan, China, in December 2019 and has spread rapidly around the world, the lack of an Food and Drug Administration-approved antiviral agent has made drug repurposing an important approach for emergency response during the COVID-19 pandemic. The aim of this study was to investigate the potential of H1-antihistamines as antiviral agents against SARS-CoV-2 RNA-dependent RNA polymerase enzyme. Materials and Methods: Using molecular docking techniques, we explored the interactions between H1-antihistamines and RNA-dependent RNA polymerase (RdRp), a key enzyme involved in viral replication. The three-dimensional structure of 37 H1-antihistamine molecules was drawn and their energies were minimized using Spartan 0.4. Subsequently, we conducted a docking study with Autodock Vina to assess the binding affinity of these molecules to the target site. The docking scores and conformations were then visualized using Discovery Studio. Results: The results examined showed that the docking scores of the H1-antihistamines were between 5.0 and 8.3 kcal/mol. These findings suggested that among all the analyzed drugs, bilastine, fexofenadine, montelukast, zafirlukast, mizolastine, and rupatadine might bind with the best binding energy (< -7.0 kcal/mol) and inhibit RdRp, potentially halting the replication of the virus. Conclusion: This study highlights the potential of H1-antihistamines in combating COVID-19 and underscores the value of computational approaches in rapid drug discovery and repurposing efforts. Finally, experimental studies are required to measure the potency of H1-antihistamines before their clinical use against COVID-19 as RdRp inhibitors.

Synthesis of Novel Thiazole/Thiadiazole Conjugates of Fluoroquinolones as Potent Antibacterial and Antimycobacterial Agents
(John Wiley and Sons Inc, 2025) Poyraz Yılmaz, P.; Kulabaş, N.; Bozdeveci, A.; Vagolu, S.K.; Imran, M.; Tatar, E.; Küçükgüzel, İ.
Twenty azole-fluoroquinolone hybrids were designed and synthesized by conjugating thiazole and thiadiazole structures to ciprofloxacin and norfloxacin via a 2-oxoethyl bridge. The structures and purities of the synthesized compounds were proven by spectral techniques. The antimycobacterial effects of target compounds 21–40 were tested against Mycobacterium tuberculosis H37Rv strain. Among the 20 synthesized compounds, 12 exhibited minimal inhibition concentration (MIC) values in the range of 1.56–25 μg/mL. Among the molecules screened for antimycobacterial effects, the most effective was compound 35, a thiadiazole-ciprofloxacin hybrid. The cytotoxic effect of this molecule was found to be lower than the reference drugs, and it was also determined to be a more effective inhibitor than ciprofloxacin and norfloxacin in the DNA-gyrase supercoiling test. The antimicrobial effects of compounds 21–40 were screened by agar-well diffusion and microdilution tests against Gram-positive/negative bacteria, a fast-growing mycobacterium, and two yeast strains. While most of the compounds tested showed antibacterial effects, the most effective fluoroquinolone derivative appeared to be compound 31 with an MIC value of < 0.63 μg/mL against all Gram-negative bacteria tested. Azole-fluoroquinolone hybrids 21–40 did not show any activity against non-pathogenic Lactobacillus species and yeast-like fungi, indicating that they have selective antibacterial and antimycobacterial activity, particularly against Gram-negative bacteria. In silico molecular docking studies were conducted to uncover the interactions between lead compound 35 and the DNA gyrase proteins of M. tuberculosis and S. aureus. Additionally, a 100 ns molecular dynamics simulation was carried out to assess the stability of the complexes formed between compound 35 and both proteins. © 2025 The Author(s).

Petroselinum Crispum Extract Prevents Scopolamine-Induced Lens Damage in Rats
(Wiley-v C H verlag Gmbh, 2023) Ertik, Onur; Pazarbasi, Seren Ede; Sener, Goksel; Sacan, Ozlem; Yanardag, Refiye
Alzheimer's disease (AD) is a neurodegenerative disease that occurs especially in advanced ages. It reduces the quality of life of both the patient and their relatives. In addition to its primary effects, AD causes metabolic defects and tissues are damaged due to these effects. Oxidative stress damages cells by disrupting antioxidant/oxidant balance in many tissues, especially due to AD. In individuals with AD and the elderly, lens tissue is damaged due to oxidative stress and may cause vision loss. Therefore, it is very important to investigate herbal products that both prevent/cure AD and reduce AD-related oxidative stress, as they may have fewer side effects. In this study, the protective effects of parsley (Petroselinum crispum) extract on lens tissues of an experimental AD model induced by scopolamine were examined and evaluated through biochemical parameters. The result of biochemical experiments and principal component analysis, was observed that parsley extract had a therapeutic effect by reducing oxidative stress in lens tissues of experimentally induced AD rats. It can be suggested that the phenolic and flavonoid-rich content of parsley extract may have caused the reduction of oxidative damage in lens tissues and can be used to protect lens tissue against oxidative stress due to AD disease.

(Elsevier, 2024) kethudaoglu, Mustafa Oguz; Ozdemir, Aysem Ecem; Saglam, Oznur Kaya; Caglar, Engin; Caglar, Meltem Meran; Demir, Gokhan; Duymaz, Tomris
Background: Presence of pes planus is known to effect balance. In this study, it was aimed to examine the immediate effects of IASTM and PMT on static and dynamic balance in young adults with pes planus. Method: The navicular drop test was used to diagnose pes planus. 51 individuals were included in the study and divided into three groups [IASTM (n:15), percussive massage (n:18) and control (n:18) groups] by simple randomization. Flamingo and Y Balance test was assessed before and immediately after intervention. Repeated Measures ANOVA test was used for the intergroup comparison, and the One -Way ANOVA test was used for the intragroup comparison, also post -hoc test with Tukey correction was performed. Results: There was no significant difference in static balance between the three groups (p > 0.05). There was a significant difference in dynamic balance between groups (p < 0.05). Only IASTM group had significant differences at before and after intervention of all directions except for posterolateral direction of Y Balance Test (p < 0.05). Conclusion: IASTM applied to the plantar fascia of individuals with pes planus have immediate effects on dynamic balance when compared to no intervention and percussive massage even within a small sample size.

Background. Understanding the severity of the disease from the parents' perspective can lead to better patient outcomes, improving both the child's health -related quality of life and the family's quality of life. The implementation of 3 -dimensional (3D) modeling technology in care is critical from a translational science perspective. Aim. The purpose of this study is to determine the effect of 3D modeling on family quality of life, surgical success, and patient outcomes in congenital heart diseases. Additionally, we aim to identify challenges and potential solutions related to this innovative technology. Methods. The study is a two -group pretest -posttest randomized controlled trial protocol. The sample size is 15 in the experimental group and 15 in the control group. The experimental group's heart models will be made from their own computed tomography (CT) images and printed using a 3D printer. The experimental group will receive surgical simulation and preoperative parent education with their 3D heart model. The control group will receive the same parent education using the standard anatomical model. Both groups will complete the Sociodemographic Information Form, the Surgical Simulation Evaluation Form - Part I -II, and the Pediatric Quality of Life Inventory (PedsQL) Family Impacts Module. The primary outcome of the research is the average PedsQL Family Impacts Module score. Secondary outcome measurement includes surgical success and patient outcomes. Separate analyses will be conducted for each outcome and compared between the intervention and control groups. Conclusions. Anomalies that can be clearly understood by parents according to the actual size and dimensions of the child's heart will affect the preoperative preparation of the surgical procedure and the recovery rate in the postoperative period.
